Equity in Business
The Denning Society Annual Lecture, Lincoln’s Inn, London
Lord Briggs of Westbourne, Justice of The Supreme Court of the United
Kingdom
8 November 2018
1. Almost exactly 20 years ago Lord Millett (then Millett LJ) published in the Law Quarterly
Review a seminal article entitled “Equity’s Place in the Law of Commerce”.1 Its main theme
was that, although equitable doctrines, remedies and principles could not be confined to the
realm of family and friendship from which they had originated, their uncontrolled extension
into the commercial field, and their unthinking application by common lawyers unversed in
the detail of their checks and balances, was in danger of doing more harm than good. It
would undermine both the desirable certainty of English commercial law and the valuable
role performed by equity in regulating the conduct of professional trustees and other true
fiduciaries, practicing in the commercial sphere. He suggested that these developments had,
even among those calling themselves equity lawyers, given rise to a worrying perception that
there simply was not that level of agreement about fundamental principle which ought to
underlie the application of equity in an ever more complex business world.
2. Despite Lord Millett’s heroic efforts to put this right, both in and out of court, I think that
this worrying perception remains, 20 years on. Most judges who pronounce on the question
agree at least that equitable principles and remedies need to be kept from getting out of
control in the market place. There continues to be a view among some commercial lawyers,
including commercial judges, that equity has arrogated to itself far too great a role in the
commercial field. The most pointed reminder to me of that more rigorous commercial view
came in the dissenting judgment of my good friend Dame Elizabeth Gloster (then Gloster
LJ) in UBS v Kommunale Wasserwerke Leipzig,2 at para 347, where she observed that by the

invocation of equitable principles the majority (including me) were impracticably and
unrealistically introducing into commercial transactions the moral standards of the vicarage.
3. I am not even going to attempt, in a single address, to provide that missing consensus about
basic principle. As Lord Walker and many other distinguished equity judges have warned (in
his case in Cobbe v Yeoman’s Row3), the trouble with broad over-arching principle is that it can
only be expressed at such a high level of generality that it provides little useful guidance in
the factually complicated world of real people, real events and real transactions. Rather, I
am going to have a look at some aspects of equity’s role in the law of business and
commerce where there have been occasions in the last 20 years to remedy Lord Millett’s
perceived lack of agreement about principle, in a way that keeps equity to its proper role. I
want to consider how successful we, that is judges, academics and advocates, have been in
doing do. The result has I think been, to adopt another expression in daily use in the
vicarage: ‘like a curate’s egg, good in parts’.
4. The starting point is to recognise that, even in as short a period as 20 years, the role of equity
in the business world has, necessarily and inevitably, increased rather than receded, or even
stood still. In the period preceding 1998 Lord Millett pointed to the growing role of
professional fiduciaries in an economy increasingly focussed upon services, including
financial services, and to the need, not met by regulation, to impose upon them higher
standards of conduct than those likely to flow from what he called the combined drivers of
“success, self-interest, wealth, winning and not getting caught” (quoting Lord Sacks).4 Chief

Justice Mason had said much the same in a lecture in 1993.5 Those factors have marched on
since then, reaching their apogee in the causes and outcomes of the 2008 crash. My own
experience, at the bar and more particularly as the London judge in charge of the litigation
about the Lehman collapse, has shown me that, in important areas, equity is quite simply the
dominant source of the relevant law, and that regulation has not, contrary to the hopes of
many, provided a satisfactory alternative.
5. Let me give two Lehman-related examples. They each demonstrate the pervasive role of
equity in the commercial field, side by side with a lack of understanding or agreement about
its principles. First, the global settlement practice of the Lehman group internationally
involved ‘hub companies’ in each time zone (such as Lehman Brothers International Europe,
or LBIE for short in London) buying, selling and lending securities to and from the street for
the economic benefit (to use a neutral term) of a large number of their affiliates worldwide.
When in 1993 Lehman set up a largely computerised process for the daily handling of those
holdings within the group, by millions of twice daily repos (a process called Rascals), the
designers did so on the assumption (which turned out to be wrong in law) that the pre-
existing regime which they were seeking to digitise already conferred proprietary beneficial
interests in the underlying securities in favour of the affiliates, rather than just an economic
stake, reflected in debt accounting obligations of the hub companies. The replication of
those arrangements by the Rascals system therefore proceeded under a common assumption
by all concerned, nowhere expressly recorded in writing in any transactional document, that
it continued to confer beneficial interests under trusts of which the hub companies were
trustees. The result was, applying settled equitable principles, that common intention trusts

(1994) 110 LQR 238.
4
arose for the first time, from the Rascals process, which governed the beneficial interests in
all the securities held by the hub companies. When, two weeks after the start of the
administration of LBIE, the administrators discovered the Rascals computer in London still
cheerfully doing thousands of twice daily transactions and ordered it to be switched off, the
terms of those trusts then governed the question who owned the securities when the music
stopped. It took a long and expensive piece of litigation, ending in the Court of Appeal, to
determine what those trusts were, and the principles by which, not only their terms, but their
very existence, should be tested.6
6. The second example is even more stark. The fiduciary basis upon which LBIE in London
held securities for its customers required, in accordance with basic equitable principle, that it
segregate its own house funds from those which it held on trust for its customers. LBIE
completely failed to recognise, (as did its regulators and auditors), that securities held for its
affiliates also needed to be segregated, since they were also its customers for that purpose.
The result was a shocking shortfall in the segregated fund which should have been available
for its customers when LBIE collapsed, aggravated by the fact that a large part of what had
been segregated was deposited in an overseas affiliate which itself went bust at the same
time. The result was a huge dispute as to who was entitled to share, and in what proportions,
in the wreckage of the segregated fund, eventually resolved by a bare majority in the Supreme
Court on a basis which Lord Walker (the only pure equity lawyer on the panel) regarded as
not only completely wrong, but as incomprehensible.7

7. You will all have experience, or easily think, of other examples, particularly in the ripe
field of commercial fraud and misconduct, where equitable principles have been found to
prevail, but where litigation has revealed a lack of agreement, at a fundamental level,
about what those principles are, or how they work. A conspicuous example is the
question whether the recipient of a bribe holds it on trust for his principal, only recently
resolved after much judicial and academic controversy, in FHR v Cedar Capital.8 I want to
concentrate on a small number of areas where the debate about principle has been
precisely concerned with the question how to set bounds upon the role of equity in
business and commerce, so as to keep its important role from getting out of hand. They
are:
a. The Pallant v Morgan9 equity, which I will use as a detailed case study.
b. The solicitors’ equitable lien.
c. Relief from forfeiture.
d. Rectification.
The Pallant v Morgan Equity
8. One of the unfortunate habits of lawyers, which continues to make the law (including
equity) impenetrable to anyone other than themselves, is their tendency to label remedies,
principles and rules by reference to the reported case in which they were first formulated,
or the section of the CPR in which they are laid down. Words and phrases like Mareva,
Walsh v Lonsdale and Part 36 unlock whole warehouses full of meaning to lawyers, but the
doors remain firmly bolted to everyone else. The Pallant v Morgan equity is one of the
more recent additions to the library of legal key -phrases, even though the decision itself

was made and reported as long ago as 1953, before I was born. The case only
contributed the label for a distinct equity many years later, I think first from Megarry J at
an interlocutory hearing in Holiday Inns Inc v Broadhead10 in 1974, when I was still reading
history and singing for my supper at university. I suspect that the judge who decided
Pallant v Morgan, Harman J (father of Sir Jeremiah), would be most surprised that this
should have happened. He thought he was just following Chattock v Muller,11 reported in
1878, with the encouragement of the then leading textbook on Specific Performance,
namely Fry (6th ed.), in an a fortiori case on the facts.
9. The plaintiff and the defendant had agreed informally that the defendant would bid at
auction, and that the plaintiff would not bid, for a property which they both wished to
buy and that, if successful, the defendant would then share it with the plaintiff in
proportions to be derived from what turned out to be an unworkable formula. The
defendant bid successfully and then sought to keep the whole of the property for
himself. Harman J regarded this as a fraud. The defendant was to be treated as having bid
on behalf of both of them, and therefore as holding the property on trust. In default of
an agreed workable sharing ratio, it was held for them in equal shares.
10. The reason why recourse has had to be made to a case name for this equity is, I suspect,
because no-one has since been able to agree upon the principled basis for its existence,
still less upon the boundaries which circumscribe its legitimate application. The trouble
started at the very beginning of the new millennium, in January 2000, when the Court of
10 (1974) 232 EG 951.
11 (1878) 8 Ch D 177.
7
Appeal, led by Chadwick LJ, had a go at defining its basis and scope, in Banner v Luff.12
Looking for an underlying principle, he said that it was:
“an example of the wider equity to which Mr Justice Millett referred in Lonrho Plc v
Fayed (No 2) [1992] 1 WLR 1, at pages 9H-10A:
“Equity will intervene by way of constructive trust, not only to compel a
defendant to restore the plaintiff's property to him, but also to require a
defendant to disgorge property which he should have acquired, if at all, for the
plaintiff. In the latter category of case, the defendant's wrong lies not in the
acquisition of the property, which may or not have been lawful, but in his
subsequent denial of the plaintiff's beneficial interest. For such to be the case,
however, the defendant must either have acquired property which but for his
wrongdoing would have belonged to the plaintiff, or he must have acquired
property in circumstances in which he cannot conscientiously retain it against the
plaintiff.”
11. Recognising that, thus stated, this principle said nothing useful about scope, or
boundaries, Chadwick LJ then laid down five (now well-known) probanda, warning that
they should not be treated as an exhaustive definition, since:
“Equity must never be deterred by the absence of a precise analogy, provided that
the principle invoked is sound.”
In outline, the probanda were that:
1) There was a pre-acquisition agreement or understanding, although pre-acquisition
might not be essential;
12 Banner Homes Holdings Ltd v Luff Developments Ltd [2000] Ch 372 (CA).
8
2) Which did not amount to an enforceable contract (either because of
incompleteness or lack of intention to contract);
3) To the effect that the non-acquiring party should obtain an interest in the
property being acquired by the other party, from which the acquiring party had
not resiled to the knowledge of the non-acquiring party before acquisition took
place;
4) That the non-acquiring party had suffered some detriment, such as not making a
competing bid, or thereby conferred some advantage on the acquiring party;
5) In circumstances making it inequitable for the acquiring party to retain the whole
of the property for himself.13
12. That was a case of an informally agreed joint venture between Banner and Luff for the
development of land, which Luff then acquired, and sought to keep for itself. The trial
judge (Blackburne J) had refused Banner a remedy because he found that the parties
understood that there needed to be a formal written contract before legal relations arose,
before the conclusion of which either side was free to resile. This did not deter the Court
of Appeal from equitable intervention by way of constructive trust. Both parties were, be
it noted, experienced business persons, and the joint venture was plainly commercial in
nature.
13. Banner v Luff was distinguished in 2002 by the Court of Appeal in London & Regional
Investments v TBI on the basis that the negotiations for a joint venture had been expressly
‘subject to contract’.14 This was, it was said, quite different from a mere ‘no contract’ case
13 Ibid, 397F-399D.
14 London & Regional Investments Ltd v TBI Plc [2002] EWCA Civ 355, [42] (Mummery LJ).
9
such as Banner v Luff, and the express use of that well-known label was sufficient to
prevent a conclusion that the acquiring party’s conduct in resiling from the joint venture
was unconscionable.15 The parties were, again, experienced in business.
14. Cobbe v Yeoman’s Row16 decided by the House of Lords in 2008 was, like Banner v Luff, a
‘no contract’ rather than subject to contract case, and again between experienced
business dealers. But the informal agreement relied upon did not precede the defendant’s
acquisition of the relevant property, which was a block of flats, ripe for development.
The deal was that the claimant would secure planning permission, and then the
defendant would sell the property to him, for a specified sum, with an arrangement to
share overage on the on-sale after its development by the claimant. The claimant
obtained the necessary planning permission, but the defendant then refused to sell to
him, otherwise than at a greatly increased price. The evidence showed that the defendant
had decided to take this course before the claimant obtained planning permission, but
kept quiet about it. It was common ground, at all levels, including the House of Lords,
that this conduct was unconscionable, by any standard.
15. Following Banner v Luff the trial judge Etherton J treated the case as essentially one of
proprietary estoppel, and upheld Mr Cobbe’s claim to a beneficial interest in the property

16 n 3.
10
under a trust.17 The Court of Appeal agreed, reinforcing the distinction between ‘no
contract’ and ‘subject to contract’ cases.18
16. It was in the House of Lords that concern about the potential for this equity to
undermine commercial certainty first clearly arose. Lord Scott (giving the speech with
which the majority agreed) started by citing this well-known dictum by Deane J in
Muschinski v Dodds19:
“The fact that the constructive trust remains predominantly remedial does not,
however, mean that it represents a medium for the indulgence of idiosyncratic
notions of fairness and justice. As an equitable remedy, it is available only when
warranted by established equitable principles or by the legitimate processes of legal
reasoning, by analogy, induction and deduction, starting from the conceptual
foundations of such principles … Under the law of this country - as, I venture to
think under the present law of England … proprietary rights fall to be governed by
principles of law and not by some mix of judicial discretion, subjective views about
which party 'ought to win' … and the 'formless void' of individual moral opinion
…"20

17. Lord Walker, concurring in the result, but with slightly different reasons, also relied
on that passage, and added:
“Equitable estoppel is a flexible doctrine which the Court can use, in appropriate
circumstances, to prevent injustice caused by the vagaries and inconstancy of
human nature. But it is not a sort of joker or wild card to be used whenever the
Court disapproves of the conduct of a litigant who seems to have the law on his
side. Flexible though it is, the doctrine must be formulated and applied in a
disciplined and principled way. Certainty is important in property transactions.”21
Later, referring to the Pallant v Morgan line of cases, he continued:
“In my opinion none of these cases casts any doubt on the general principle laid
down by this House in Ramsden v Dyson (1866) LR 1 HL 129, that conscious reliance
on honour alone will not give rise to an estoppel. Nor do they cast doubt on the
general principle that the court should be very slow to introduce uncertainty into
commercial transactions by over-ready use of equitable concepts such as fiduciary
obligations and equitable estoppel. That applies to commercial negotiations whether
or not they are expressly stated to be subject to contract.”22
And he concluded:
“In my opinion the Court of Appeal's decision, if it were to stand, would tend to
introduce considerable uncertainty into commercial negotiations, and not only in
the field of property development … Equity has some important functions in
21 Ibid, [46].
22 Ibid, [81].
12
regulating commercial life, but those functions must be kept within proper
bounds.”23
He ended by referring to Lord Millett’s article in the LQR.24
18. Their lordships then proceeded to reject Mr Cobbe’s proprietary claim, leaving him to a
much less valuable quantum meruit.25 They clearly did not outlaw Pallant v Morgan claims
altogether, but there has been much debate about the metes and bounds which they
erected, in order to avoid the damage to commercial certainty about which they were
primarily concerned. Nor has any clear consensus emerged as to the principled basis for
the Pallant v Morgan equity, either from Cobbe itself or from the succession of Court of
Appeal cases which have ensued, right through to this year. What follows is a necessarily
potted summary.
19. In Cobbe, Lord Scott drew a sharp distinction of principle between proprietary estoppel
and constructive trust as the basis for the Pallant v Morgan equity, regarding it as the
creature of the latter.26 Although he did not spell out why, it seems to me that, unless
(heaven forbid!) it was to be a remedial constructive trust, it therefore depended upon
the informal joint venture arrangement preceding the acquisition of the property by
either party. Otherwise, there was nothing to impress the property with a trust when
acquired by the defendant. There being no pre-acquisition agreement, Mr Cobbe’s case
therefore depended in Lord Scott’s view upon proprietary estoppel. But there could be

24 Ibid, [85].
25 Ibid, [42]-[45] (Lord Scott), [93] (Lord Walker).
26 Ibid, [30].
13
no estoppel where business counterparties knew that, pending a binding written contract,
either side was free to withdraw, regardless whether they used the phrase ‘subject to
contract’ in their dealings. It has since been said that this decision largely confines
proprietary estoppel to the family, or at least non-business sphere. Lord Scott added obiter
that the failure of Parliament to exempt proprietary estoppel from s.2 of the Law of
Property (Miscellaneous Provisions) Act 1989 has killed it off altogether, whether or not
in a business context.27 Whether that is right or not goes beyond the scope of this
address.
20. Lord Walker drew no such clear classification between proprietary estoppel and
constructive trust, and appears to have considered that, in Banner v Luff, Chadwick LJ
regarded the equity as a species of the former.28 But in his view Mr Cobbe’s case
trespassed across a boundary fencing off any kind of equitable claim, namely that
enshrined in the famous dictum of Lord Cranworth in Ramsden v Dyson:
“If any one makes an assurance to another, with or without consideration, that he
will do or will abstain from doing a particular act, but he refuses to bind himself,
and says that for the performance of what he has promised the person to whom the
promise has been made must rely on the honour of the person who has made it,
this excludes the jurisdiction of Courts of equity no less than of Courts of law."29
Since honour was how Mr Cobbe had described the bond between the parties, that
was the end of the matter.30

29 Ramsden v Dyson (1866) LR 1 HL 129, 145.
30 Cobbe (n 3), [91] (Lord Walker).
14
21. Both Lords Scott and Walker clearly regarded the Pallant v Morgan equity as confined to
failed joint ventures, and they had no difficulty in treating the arrangements between the
parties before them as a joint venture in that sense. That general description is likely to
apply to any arrangement where, for mutual profit, one party contributes the relevant
property while the other provides relevant business expertise or experience. It is
therefore a bit surprising that neither of them cast any doubt on either the reasoning or
the result in Banner v Luff, although they both referred to it. It was a failed joint venture
case in which the commercially experienced participants clearly assumed that there would
have to be a written contract between them before legal relations were engaged. That was
the precise basis upon which Blackburne J had dismissed the claim at trial. The only real
point of distinction was that in Banner v Luff the joint venture arrangement preceded the
acquisition of the property by either of them, but Chadwick LJ had made it clear that this
was not an essential feature of the equity.
22. The next milestone in this tortuous story is Crossco No.4 v Jolan, in 2011.31 It was about a
negotiated demerger of a previously united family business, part of which went wrong. It
was not in substance about a pre-acquisition joint venture arrangement and, in any event,
the claim to a Pallant v Morgan equity failed for other reasons on the facts.32 But there was
an interesting disagreement about the principled basis of the Pallant v Morgan equity, with
real importance for its potential effect in a business context. All three members of the
Court of Appeal agreed that because of the non-disapproving way in which Banner v Luff
was dealt with in Cobbe, they remained bound by it. The majority (Arden LJ and
McFarlane LJ) felt reluctantly constrained not only by the result, but by the reasoning,
31 Crossco No.4 Unltd v Jolan Ltd [2011] EWCA Civ 1619; [2012] 1 P & CR 16.
32 Ibid, [107]-[109] (Etherton LJ), [123] (McFarlane LJ), [131]-[132] (Arden LJ).
15
which (in their view) established that a Pallant v Morgan constructive trust must be an
institutional constructive trust established by common intention, as per Gissing v Gissing,
but living and breathing in a business rather than domestic context.33
23. Etherton LJ thought that common intention trusts of that type were, because of their
policy basis, confined to the domestic sphere, by Stack v Dowden and Jones v Kernott. He
said:
“In a commercial context, it is to be expected that the parties will normally take
legal advice about their respective rights and interests and will normally reduce their
agreements to writing and will not expect to be bound until a contract has been
made: see, for example, Lord Walker in Cobbe at [68] and [81]. They do not expect
their rights to be determined in an "ambulatory" manner by retrospective
examination of their conduct and words over the entire period of their relationship.
They do not expect the court to determine their respective property rights and
interests by the imputation of intentions which they did not have but which the
court considers they would have had if they had acted justly and reasonably and
thought about the point.”34
24. In his view, the principled basis for the Pallant v Morgan equity lay in breach of fiduciary
duty. In other words, it would arise only if, at the time of the acquisition of the property
by the defendant, he owed some fiduciary duty to the claimant which prohibited him
from acquiring the whole beneficial interest for himself. That might arise from a prior
agency, or from a partnership, but only exceptionally from a commercial joint venture. In
his view, Pallant v Morgan itself was an agency case.35
33 Ibid, [122] (McFarlane LJ), [129]-[130] (Arden LJ).
34 Ibid, [87].
35 Ibid, [88].
16
25. Now is not the time to engage with the question whether the common intention trust has
any place in the business sphere, a subject about which many (if not most) equity lawyers
are likely to harbour strong, even passionate, opposing views. But even if it does have a
place (as was held in the Rascals case36), that does not, of itself, mean that Sir Terence’s
analysis of the Pallant v Morgan equity is wrong. Nonetheless it may harbour its own
uncertainties, and capacity for equitable mission-creep. If its main sphere of operation is
the commercial joint venture, by what yardstick do we decide which joint ventures do,
and which do not, impose fiduciary duties upon the participants? And what fiduciary
duties? That is another contentious question worth a lecture in itself, probably centred
around two recent cases about Ross River, in 2007 and 2013.37 Lord Millett would
probably say it’s not a question of imposition of duty, but of what they have agreed. But,
if (as has to be assumed) their agreement is incomplete, subject to contract or otherwise
unenforceable, does that take you much further?
26. This year has seen two further essays into this conundrum by differently constituted
Courts of Appeal. In the first, Farrar v Miller,38 the parties were already both indirectly
interested in the property in issue, through shareholdings in companies, although the
joint venture arrangement between them may be said to have preceded a relevant further
acquisition. The appeal concerned striking out and permission to amend, rather than
conclusions made at a trial. Nonetheless the Court of Appeal loyally adhered to the view
of Chadwick LJ in Banner v Luff that a pre-acquisition agreement was only typical, rather
36 n 6, [243]-[247] (Briggs J).

17
than essential, in creating the equity.39 Furthermore they acknowledged it as at least
arguable that the same facts might support all three claims: proprietary estoppel,
constructive trust and breach of fiduciary duty.40 Kitchin LJ (now Lord Kitchin) based
his approach to the underlying principle on the even more general dictum of Millett LJ
(in Paragon Finance Plc v D B Thakerar & Co41) that:
“A constructive trust arises by operation of law whenever the circumstances are
such that it would be unconscionable for the owner of property (usually but not
necessarily the legal estate) to assert his own beneficial interest in the property and
deny the beneficial interest of another.”42 (Emphasis added.)
27. The second, most recent case (as far as I am aware), was Generator Developments v LIDL,43
another case where the alleged joint venture agreement preceded the acquisition of the
relevant property. In upholding the trial judge’s refusal to afford the claimant a Pallant v
Morgan equity, Lewison LJ came much nearer to recognising the strictures laid down in
Cobbe as applying in a Pallant v Morgan context than in any of the intervening cases in the
Court of Appeal. He treated the absence of a pre-acquisition agreement in Cobbe as by
no means decisive,44 and cast real doubt both on the analysis and part of the five probanda
in Banner v Luff.45 But there were enough conventional reasons for dismissing the appeal

18
that his dicta would struggle to amount to a sufficient ratio, on their own, to displace
Banner v Luff and the succession of Court of Appeal cases in which it has been approved
and held to be binding.
28. So, where does this story leave the conscientious advisor, whose client has been deprived
of an expected interest in property subject to an intended joint venture, where the
conduct of his counterparty has been at least dishonourable? Perhaps another airing in
the Supreme Court is due but not, please (as was tried unsuccessfully in Farrar v Miller),
only on the fragile pleaded platform attacked by a strike-out application. There is not
often any substitute for the full tapestry of facts found at a trial.
29. I am now going to leave the Pallant v Morgan equity and look, much more briefly, at two
other areas of equitable intervention in business relations where, during the last 20 years,
the search for boundaries by reference to principle may be said to have been, perhaps, a
little more coherent. The underlying theme is not so much that new boundaries have
been formulated, but that existing principles sufficiently provide them already, and that
those principles should be firmly adhered to.
The Solicitor’s Equitable Lien
30. This equitable tool, really an equitable charge rather than a lien in the strict sense, was
formulated by courts of equity as long ago as the 18th century, to remedy a glaring
deficiency in the common law retaining lien as a means whereby the successful plaintiff’s
solicitor acting on credit could ensure that he got paid his fees. This was a business
context, even if the litigation in which the solicitor acted was a purely family matter.
19
From the earliest times it was designed to promote access to justice, by encouraging
solicitors to pursue meritorious claims for clients who lacked the means to pay fees up
front. The deficiency in the common law retaining lien was that it depended upon the
solicitor having valuable property of the client in his hands (such as the proceeds of a
paid judgment debt, recovered securities or title deeds) when the proceedings ended and
he sought payment. His client might collude with the defendant to cheat him out of his
fees by the defendant paying the claimant direct, either after judgment or following a
settlement agreement.
31. Equity could not treat the solicitor as entitled to a share in the fruits of the litigation: that
would be maintenance or champerty, although that fetter may now have been removed.
But it could, and did, treat those fruits as a fund, to which the solicitor had a proprietary
claim by way of security for payment of the client’s debt to him. Then, if there was
collusion to cheat the solicitor of his fees, or if the defendant had notice of the solicitor’s
interest in the fund, before it was paid direct to the plaintiff, equity could intervene by
acting in personam against the defendant, by making him pay the fees amount (if necessary
a second time) direct to the plaintiff’s solicitor.
32. It is of course true that, at a high level of generality, the incentive for equity’s
intervention lay in the recognition of unconscionable conduct by the defendant, but this
was not, on its own, a sufficient basis for intervention by the recognition and then
enforcement of an equitable charge. There had to be an underlying debt (owed by the
plaintiff to the solicitor), since otherwise there was nothing to secure. There had to be a
fund, to which the security could attach, namely the fruits of the litigation. Equity
would recognise the chose in action constituted by an unpaid judgment debt as a fund, or
20
part of a fund, for that purpose. Fees in excess of the amount or value of the fund were
irrecoverable by this means. The defendant had to have prior knowledge or notice of the
solicitor’s equity, before his conscience could be bound. The defendant’s personal
liability to the solicitor arose from dealing with that fund inconsistently with the
solicitor’s proprietary interest in it, usually by paying the plaintiff direct.
33. These checks and balances worked without criticism or much comment for many years,
but in Gavin Edmondson Solicitors v Haven Insurance46 they came under review in the context
of modern ways of funding litigation by no win no fee agreements, specifically the ‘CFA
Lite’, coupled with the voluntary use of the online RTA Portal as the means of settling
small PI claims under a structure of fixed fee stage payments to claimants’ solicitors. The
casus belli was a policy decision by a particular motor insurer to settle with claimants and
pay direct, after the claimant had retained a solicitor who had posted details of the claim
on the Portal.
34. The problem with the traditional equitable lien, so thought the Court of Appeal,47 was
that the CFA Lite retainer agreement imposed no contractual liability on the claimant for
the solicitor’s charges. But they decided to ignore this obstacle. Their analysis was that
the solicitors had an entitlement to payment under the Portal scheme, of which the
defendant’s insurers had notice, or that the claimant had such an entitlement which the
solicitors could enforce using the claimant’s name.48 They recognised that success for the
46 Gavin Edmondson Solicitors Ltd v Haven Insurance Co Ltd [2018] UKSC 21; [2018] 1 WLR 2052.
47 [2015] EWCA Civ 1230; [2016] 1 WLR 1385.
48 Ibid, [29] (Lloyd-Jones LJ).
21
solicitors would involve an extension of the equitable principle, but saw no reason why it
should not apply, so as to provide a remedy for the unconscionable conduct of the
insurer.49
35. Happily (in terms of deterring unconscionable conduct) the Supreme Court was able to
detect in the CFA Lite retainer a sufficient contractual liability of the claimant for the
solicitor’s fees, to be able to recognise and enforce the equitable lien on strictly
traditional grounds, without acceding to the solicitor’s invitation, supported by the Law
Society as intervener, to deploy an equitable form of intervention on a much wider and
unprincipled basis. The tempting submission was that:
“the flexibility of the equitable remedy for the protection of solicitors was apt to
respond to any instance of unconscionable conduct by the insurer, including breach
of the RTA Protocol, all the more so because of the strong public policy in
enforcing the scheme, designed as it was to balance the competing interests of its
stakeholders while ensuring access to justice for the victims of road accidents at
proportionate cost.”50
36. The Supreme Court was having none of this. Giving the leading judgment, I said:
“I acknowledge that equity operates with a flexibility not shared by the common
law, and that it can and does adapt its remedies to changing times. But equity
nonetheless operates in accordance with principles. While most equitable remedies
49 Ibid, [31] (Lloyd-Jones LJ).
50 n 46, [56] (Lord Briggs).
22
are discretionary, those principles provide a framework which makes equity part of
a system of English law which is renowned for its predictability… It is simply
wrong to seek to distil from those cases a general principle that equity will protect
solicitors from any unconscionable interference with their expectations in relation
to recovery of their charges.”51
37. Goodness knows what we might have done if we had not been able to detect a
contractual liability for the fees, or (like the trial judge) had found that the insurer did not
have notice of the lien. I can only hope that we would have comforted ourselves with the
reflection that hard cases make bad law.
Relief from Forfeiture
38. My second short example of equity suitably confined by long standing coherent principle
is relief from forfeiture. This ancient form of equitable intervention takes the form, not
of creating an equitable security, but of treating certain common law rights, however
expressed, as if they were no more than security for performance a lesser obligation, and
then restraining their use where the underlying obligation could be enforced or satisfied
by less draconian measures. Its main operation in modern times lies in the now mainly
statutory provision of relief from the forfeiture of leases, and in restraining foreclosure
by mortgagees, by enforcing the equity of redemption.
39. The recent decision of the Supreme Court in the conjoined appeals Cavendish Square v
Makdessi and Parking Eye v Beavis52 is rightly regarded as a watershed case about the
51 Ibid, [57]-[58].
52 Cavendish Square Holding BV v Makdessi and ParkingEye Ltd v Beavis [2015] UKSC 67; [2016] AC 1172.
23
common law doctrine of contractual penalties, even if, rightly or wrongly, it is regarded
by some other (overseas) common law jurisdictions as a step in the wrong direction.
However that may be, equity lawyers might do well to note with caution Lord
Neuberger’s and Lord Sumption’s comprehensive joint historical introduction, in which
they point out that the penalties doctrine shares common equitable ancestry with relief
from forfeiture.53 If the penalties doctrine can be modernised by a new broom which
erects legitimate business purpose as the basis for upholding penalties, why should not a
similar revolutionary change not be applied to the basis for upholding forfeitures,
including foreclosures. A similar fate has already befallen and curtailed the anti-
deprivation principle, leaving it a mere shadow of its former self: see Belmont Park
Investments v BNY Corporate Trustee Services.54
40. The need for caution arises not merely from common equitable ancestry. Both doctrines
have from the earliest times treated the offending item (penalty, forfeiture or foreclosure)
as in substance a security for the performance of a primary, but less draconian,
obligation. But there is some reason to hope that the equitable relief may already have
acquired sufficient metes and bounds to enable it to survive without radical reform in the
modern common law business world, unlike its common law stable-mate. That hope
comes from the recently reported but earlier decision of the Privy Council in Cukurova
Finance v Alfa Telecom,55 on appeal from the Eastern Caribbean Court of Appeal. Four
members of the Committee were also part of the seven-judge court which later decided
Cavendish Square.

UKPC 25 (reported together in [2016] AC 923).
24
41. The Cukurova case concerned a contractual power to appropriate shares, charged by
equitable mortgage to secure repayment of a loan, entitling the chargee (after the
borrower’s default and the acceleration of the due date for payment) to take over
beneficial ownership of the shares on having their then value applied in reduction of the
loan. The chargee’s real purpose in making the secured loan had always been, in
anticipation that the borrower would default, the acquisition of control over the
company in which the shares were held. Default and acceleration duly occurred, the
lender gave notice of appropriation, but the borrower obtained alternative finance for the
whole loan and sought relief in equity. The power to appropriate was neither a
foreclosure not a forfeiture in a literal sense, but it was sufficiently analogous with both
to make equitable relief in principle available. This was because, flatly contrary to the
lender’s subjective intention, the power to appropriate was, viewed objectively, inserted
by way of security for performance of the primary obligation to repay the loan.
42. The principles delimiting this form of equitable intervention, fully applicable to
commercial cases, were extracted from Lord Wilberforce’s classic summary in Shiloh
Spinners v Harding:
“it remains true today that equity expects men to carry out their bargains and will
not let them buy their way out by uncovenanted payment. But it is consistent with
these principles that we should reaffirm the right of courts of equity in appropriate
and limited cases to relieve from forfeiture for breach of covenant or condition
where the primary object of the bargain is to secure a stated result which can
effectively be attained when the matter comes before the court, and where the
forfeiture provision is added by way of security for the production of that result.
The word 'appropriate' involves consideration of the conduct of the applicant for
relief, in particular whether his default was wilful, of the gravity of the breaches, and
25
of the disparity between the value of the property of which forfeiture is claimed as
compared with the damage caused by the breach.”56
To this the Board added the caveat, extracted from The Scaptrade,57 that equity acted
only in relation to proprietary or possessory rights, not mere contractual
obligations.58
43. The rival arguments facing the Privy Council were (i) that the unconscionable collateral
purpose of the lender was itself sufficient to justify the intervention of equity and (ii) that
there could be no equitable relief at all in the absence of bad faith, of which the lender
had been acquitted. Applying settled principle based upon English law the Board of five
senior Supreme Court Justices steered a traditional path between those extremes,
granting relief on conventional grounds, fully cognisant of the commercial context in
which the dispute arose. Collateral purpose was never, in their view, a sufficient reason
on its own to inhibit the enforcement of security rights in accordance with their terms.59
In a fiduciary context the position is the opposite: see Eclairs Group v JKX Oil & Gas.60
But, following Dillon LJ in BICC v Burndy,61 they held that the mere fact that the
transaction is commercial in nature does not preclude relief from forfeiture of possessory
or proprietary rights rather than purely contractual rights.62

other [result] would restrict the exercise of a beneficent jurisdiction without any
rational justification.”63
Rectification
44. I return now to another not so good part of the curate’s egg, namely rectification. This is
an aspect of equity’s armoury where recent decisions (i.e. since 1998) may be said
positively to have widened, rather than restricted or merely confirmed, its scope in the
commercial environment, and with what many regard as serious and (probably)
unintended consequences in terms of reducing business certainty. This change is capable
of being the subject of very different lengths of analysis. For a long and admirable
review, read chapter 3 of the second edition of Hodge on Rectification. At the tail end of this
address I merely want to focus on the consequences of the new doctrine which I would
say, pace Lord Hoffmann, effected by obiter dicta what many judges and academics regard
as an earth-shattering change in a previously quiet and untroubled area of the law.
45. Prior to July 2009, when the House of Lords handed down judgment in Chartbrook v
Persimmon Homes,64 rectification required a common (or sometimes unilateral) mistake as
to the drafting of the parties’ agreement, such that it failed to reflect their prior and
continuing common intention about the matter in question, of which there was some
outward expression of accord. Under this formula, the reference to common and
continuing intention was to the parties’ true i.e. subjective intention, albeit it would
63 On Demand Information Plc v Michael Gerson (Finance) Plc [2002] UKHL 13; [2003] 1 AC 368, [29].

27
usually be proved and tested by what they had previously written, said or done. A
defendant to a rectification claim could therefore succeed by showing that the concluded
agreement did in fact reflect his intention, provided that he had not acted
unconscionably, e.g. by concealing a mistake about the non-implementation in the
document of his counterparty’s different intention, of which he was aware.
46. In his speech in Chartbrook (and not for the first time) Lord Hoffmann proposed a
critical change in the nature of the necessary mistake. Previously he had been overruled
on this very point by his colleagues (in Britoil v Hunt Overseas Oil).65 No longer was the
signed contract to involve a mistaken departure from actual common intention, but
rather a mistaken departure from the deemed common intention to be arrived at from
the purely objective construction of the parties’ last expression of accord about the
matter in question.66 The result is that a party can now obtain rectification where
previously he could not, in particular in a case where, in fact, and as in Chartbrook, the
parties were never truly ad idem about the matter in issue.
47. Let me illustrate this by a simple example. Party A wishes during commercial
negotiations to achieve a particular result ‘X’ about a matter in issue. Party B wishes to
achieve a different result ‘Y’ about the same issue. In a draft contract, each party believes
that he has achieved his objective. On its true construction the draft prescribes result Y.
The agreement as signed (without further negotiation on the matter in issue) then uses
slightly different words which, on their true construction, prescribe result X, which has,
65 Britoil Plc v Hunt Overseas Oil Inc [1994] CLC 561 (CA).
66 See Chartbrook (n 64), [59]-[65] (Lord Hoffmann).
28
all along, been A’s objective. But B is dissatisfied about the construction of the signed
agreement and sues for rectification. Neither side has behaved unconscionably towards
the other. They both separately thought that both the draft and the agreement as signed
achieved their different objectives. There was never any consensus between them on the
substance of the point. A was wrong about the meaning of the draft, and B was wrong
about the meaning of the contract as signed. Their only common mistake was their
assumption that the agreement as signed meant the same as the draft. But on the new
formulation of the equity, B gets rectification, and achieves his objective. And it would
make no difference if there had been several earlier drafts which, on their true
construction, prescribed result X. The party benefited by the final draft takes all. On the
doctrine as previously understood, B would have failed, as the claimant did in Chartbrook,
both at trial and in the Court of Appeal, because there never was any consensus about
the matter in issue, nor unconscionable conduct by A, and because the agreement as
signed reflected A’s intention.
48. Now you may ask, (as many commentators have asked), why in justice or in equity
should a party with a final draft in his favour prevail over the counterparty with the
benefit of the agreement as signed, in the absence of any true common intention about
the point in issue, or any unconscionable conduct? But the question I want you to ask
yourselves is different: why should that new and different outcome serve the promotion
of certainty in business dealings?
29
49. Both Prof Paul Davies67 and Marcus Smith68 (now Mr Justice Smith, but speaking pre-
judicially) have suggested that the Chartbrook approach will lead to more, rather than less,
contracts being rectified. Commercial parties frequently have lengthy negotiations about
complex contracts, running to many drafts. Equally frequently they do not in fact reach a
true (i.e. subjective) consensus on important points. That is, as Lord Hoffmann himself
acknowledged in the same case, precisely why we construe contracts objectively, and
exclude evidence of the parties’ negotiations. That process serves the cause of certainty
in English law. The parties negotiate, and prepare drafts, on a subject to contract basis,
intending only to be bound by the final, signed version, whatever it means on its true
construction. If they never reached a common intention which differs from the meaning
of the signed contract, objectively construed, and no unconscionable advantage has been
taken by one party over the other, why is certainty served by permitting a claim for
rectification to succeed where previously it would have failed?
50. My concern that, in this field, equity may have taken a course which detracts from
commercial certainty is borne out by the messy outcome of the first case in which the
Court of Appeal applied this new doctrine, Daventry DC v Daventry & District Housing
Ltd.69 The Chancery trial judge (Vos J) refused rectification, and one Chancery member
of the Court of Appeal (Etherton LJ) agreed with him. But rectification was ordered on
appeal by Lord Neuberger MR and Toulson LJ. They all agreed to apply Lord
Hoffmann’s objective test, although that distinguished (and sadly now deceased)
67 Paul S Davies, “Rectification versus interpretation: the nature and scope of the equitable jurisdiction” (2016) 75(1)

30
common law judge Lord Toulson questioned whether it was correct, for exactly the
same reasons as flow from the AB / XY example which I have given.70
51. It became very clear that the adoption of an objective approach to the identification of
the prior common intention by no means excluded the pleading and forensic analysis of
the parties’ subjective beliefs and intentions, because the claimant still needed to show,
and the defendant deny, that the departure in the agreement as signed from the accord
derived from construing the final draft was a mistake, rather than a negotiated change of
position. Furthermore it is evident that the majority in the Court of Appeal were heavily
influenced by their very dim moral view of the conduct of the defendant’s principal
negotiator, a point upon which they differed at least in degree from the trial judge and
Etherton LJ. So the morals of the vicarage may be said by some to have had their sway,
even there.
Conclusions
52. I want finally to explore the question whether this one long and three short forays into
the operation of equitable remedies in the commercial field tells us anything in general
about how the working of equity should be defined and delimited, so as to avoid
undermining commercial certainty. I think that the lessons to be learned may include the
following.
53. First, defining the underlying equitable principle too broadly, or at too high a level of
abstraction, helps no-one, even if it may generate a comfortable glow of legal uniformity
70 Ibid, [104] (Etherton LJ), [117], [176]-[182], [185] (Toulson LJ), [195]-[196] (Lord Neuberger MR).
31
in the mind (or heart) of the speaker and of the incautious listener. To say, as Lord
Millett did, in the Paragon case, that “a constructive trust arises whenever it would be
unconscionable for the legal owner of property to assert his own beneficial interest and
deny the beneficial interest of another” (emphasis added) begs more questions than it
answers. Lord Millett was using that compendious expression not by way of definition,
still less for setting metes and bounds, but as the loose description of a cake which he
intended then to cut into two very distinct slices. Unconscionable conduct may be a
minimum condition, but never a sufficient condition, for the intervention of equity. In
my respectful view its use in Farrar v Miller in connection with the boundaries of the
Pallant v Morgan equity led potentially to an uncontrolled invasion of equity into
commerce. So, in practice, would the Court of Appeal’s approach to the equitable lien in
Edmondson v Haven, if the Supreme Court had not nipped it in the bud.
54. Of course equity is the creature and the enforcer of good conscience, of which the
unconscionable businessman should, like anyone else, tread in fear, in particular when
entrusted with someone else’s property or affairs as a fiduciary. Recourse to basic
principles like unconscionable conduct does sometimes help, in particular in preventing
equity being reduced to a set of arcane rules, and becoming detached from its
fundamental purpose. This detachment of equitable relief from its purpose of enforcing
the dictates of conscience may have happened in relation to rectification. It appears that
the super-imposition of common law contractual construction principles upon
rectification has blurred the line between the objective approach of the common law to
construction and the previously more subjective (and conscience-driven) equitable
jurisdiction for rectification. Equity has lost its way in rectification because it has
forgotten that the defendant with a clear conscience should, in general, be immune from
equitable relief. The irony is that, in doing so in the context of rectification, its recent
32
unprincipled intervention in the commercial sphere has reduced, rather than increased,
commercial certainty.
55. For the same reason broad, general statements about the need for certainty in business
and commercial relations and for the need for equity to tread carefully in that field,
however desirable as a goal, do little to enlighten us about the way of achieving it. There
can be no general principle which ring-fences all commercial dealings from equitable
intervention. Nor is it right that there is less need for the intervention of equity in
business rather than personal or family relationships. Business people can be just as
abusive, unconscionable and plain beastly to each other as members of a family.
56. Rather, the imposition of appropriate metes and bounds needs to be based upon sound
principles derived, usually incrementally, from the way in which equity actually works to
provide a remedy in recognised classes of commercial cases. The comparative
workability of the law on relief from forfeiture and the solicitors’ equitable lien, when
compared with the less satisfactory state of the law on the Pallant v Morgan equity and
rectification, can arguably be explained on the basis that the former two doctrines have
clearly defined threshold conditions, which are themselves properly rooted in principle.
In the case of relief from forfeiture, the minimum requirement is a proprietary or
possessory interest, regardless of whether the context is familial or commercial: see
Cukurova. This requirement flows from treating forfeiture of that interest as only a
security for the performance of some lesser obligation.
57. As to the solicitors’ equitable lien, the requirements are a sufficient contractual liability
for the solicitors’ fees on the client’s part, together with a fund in which the solicitor can
33
assert a proprietary security interest of which the defendant has notice. These
requirements flow directly from identifying the lien as a form of equitable charge.
Importantly, they prescribe minimum conditions for the application of equity, without
operating in a rigid manner. In both cases, the requirements derive from principle, while
leaving some, but not too much, room for flexible development.
58. In contrast, the authorities on the Pallant v Morgan equity illustrate how a genuine attempt
to identify flexible metes and bounds can go wrong, when it is insufficiently anchored in
a principled examination of how the particular equity works. Chadwick LJ’s five probanda
in Banner v Luff were an heroic attempt to make what turned out to be bricks without
straw, based on only a tiny handful of cases. Upon later analysis they could not be
explained in terms of how the equity actually worked. Was it based on (i) estoppel, (ii)
constructive trust, and if so institutional or remedial, or (iii) breach of fiduciary duty, and
if so, by reference to what criterion for the identification of such duties in a joint venture
relationship, short of a conventional agency? Then, in Cobbe, their Lordships really just
evaded the problem of definition by making the assumption, without explaining why,
that the absence of a pre-acquisition agreement made all the difference. The result was a
forceful assertion of the need for commercial certainty, but no explanation how, in a
genuine pre-acquisition scenario, it was to be achieved.
59. There is therefore a need to formulate with considerable clarity and specificity the
principles which, cumulatively, justify equity’s intervention in a particular type of
commercial context, subject to a baseline or overarching requirement of unconscionable
conduct, operating at a higher level of generality. The general requirement serves only to
prevent the misapplication of equitable remedies where they have no role at all to play,
